Padgett ,   et al. | July 23, 1996 |
The apparatus of the present invention includes a mixing tube and inlets for conveying substances into the mixing tube such that the components intersect at a common point. A replaceable insert directs a dry component into the mixing tube. A liquid inlet bi-directionally sprays a liquid component between a wall of the mixing tube and the insert and toward the common point. A recirculation inlet directs a recirculated component toward the common point. Mixing is enhanced by a flow deflector and a flow interceptor which converge and turn the substances. The method of the present invention includes conveying substances into a mixing tube and intersecting the substances at a common point in the mixing tube to form a mixture.
